How Safe is an NBA Lead in the 2016-17 Season

Here is an update on how safe an NBA lead is for the 2016-17 NBA Season. Last season, we found that the Bill James’ bound was violated twice in the 2015-16 NBA season. This year, the bound was violated one time: January 4th, 2017 by the Miami Heat against the Sacramento Kings. The same Sacramento Kings who erased a 15 point lead over the Oklahoma City Thunder on the same day in 2016!

Distribution of Time to Comeback

Here, we again plot a mere 10% of the occurrences of comebacks in the NBA season. It’s a cluttered plot if we add more. There was only one instance all season, indicating a 99.999+% success rate in the Bill James bound.

One thing is clear… be wary of the Sacramento Kings on January 4th games. They will erase large deficits.
